WATCH.

Specification of Letters Patent.

Patented Mar. 9, 1920.

' Application filed December 12, 1918. Serial No. 286,382.

is to provide a watch with a plurality of.

transparent closures so positioned and a:- ranged as to give the :hands and dial a permanent protection with an unrestricted view. A further object is to provide a simple and practical watch crystal adapted to withstand hard usage and yet possess all the advantages of the usual glass crystal without the disadvantages such as caused by the small particles of glass getting into the works of the watch on breakagexof the crystal.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof, all as morecompletely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed as a part of this disclosure, and in such drawings, like characters of reference denote corresponding parts throughout all the views, in which Figure 1 is an enlarged transverse sectional view showing the bezel and crystal in operative position;

Fig? 2 is a similar view showing a modified arrangement of the same parts;

Fig. 3 is a similar view showing a modified form of crystal, the view including parts of the watch casing in elevation;

Fig. 4 is another view similar to Fig. 1 with-a modified form of crystal.

Referring to the drawings in detail and more particularly to Fig. 1, 10denotes the usual bezel of a watch casing which may be of any desired type according to the style of watch to which it is applied. llhe curved portion 11 of this bezel is provided with an indented annular seat 12 adapted to receive a crystal preferably made up of two parts. The inner part or member 13 is of celluloid or other transparent material.

having a certain amount of flexibility to withstandshocks and capable of being easily and inexpensively manufactured. Immediately adjacent this sheet 13 is a. glass crystal 14 of substantially the same size. .Both

of these-members are adapted to be sprung into the indented groove 12 of the bezel in the usual manner.

VVhe-n the parts are positioned as herein described andshown, the celluloid crystal 13 .will hold the glass crystal 14 in relatively fixed; position thereby to .prevent rattling which will eventually cause such wear around the periphery as to admit dust to the interior of the casing. At the same time the celluloid sheet 13 acts as a strengthening member which will reinforce the'crystal 14 and should the latter be broken at any time the resiliency of the member 13 will prevent breakage thereof from ordinary shocks and the subsequent entering of small pieces of glass to the interior of the casing.

In Fig. 2, the bezel 10 is provided with two seats or indented annular grooves 15 and 16 respectively and the crystals of celluloid and glass, 13 and 14, are sprung into these respective grooves successively. In this arrangement it will be noted that there is a slight space left between the two crystals.

In Fig. 3, the bezel 10 is of the usual construction adapted to hold the glass crystal 14. and the celluloid crystal 13 is provided with a downwardly turned flange 17 adapted to rest on the watch casing within the bezel as clearly shown. This construction, it will be seen, is applicable to watches now in general use without material modification.

In Fig. 4., the bezel 10 is provided at its upper edge with inner and outer seats 18 and 20 respectively, adapted to receive the crystal 13 of celluloid and the crystall of glass. In both modifications shown in Figs.

3 and 4c there is a space provided between the two crystals which acts as a dust proof at least with very slight change in the bezel only, according to the type employed. The celluloid crystals may be easily and inexpensively manufactured and applied and the invention as a whole is believed to accomplish, among others, all the objects and advantages herein set forth.

While I have herein specified the crystals as being made of glass and celluloid, it is of course to be understood that these terms are to be given a broad and general interpretation, for various other materials might be employed.

I realize that considerable variation is possible in the details of construction and arrangement of parts without departing from the spirit of my invention, and I therefore do not intend to limit myself to the specific form shown and described.

I claim:

1. In a watch construction, in combination, a bezel provided with annular seating means, an outer crystal of hard mar-resisting transparent material, and an inner crystal of transparent flexible substantially non-breakable material mounted in said annular seating means.

2. In a watch construction, in combination, abezel provided with annular seating means, an outer crystal of hard mar-resisting transparent material, and an inner crystal/of transparent flexible substantially nonbreakable material independently mounted in said annular seating means.

' In a watch construction, in combination, a bezel, two annular seating means formed in the bezel, a crystal of hard marresisting transparent material mounted in apart whereby an air chamber is formed between them. 7 V

In testlmony whereof I affix my signature in presence of two witnesses.
